Leaders from the Communist Party of India and Communist Party of India-Marxist on Friday moved privilege motions in the Lok Sabha seeking unqualified apology from Trinamool Congress leader Mamta Banerjee, who flung a bunch of papers at the Speaker's podium on Thursday alleging that she had been deliberately denied a chance to to speak.

The ruling United Progressive Alliance, its Left party allies and supporters have condemned what they termed as the 'wild behaviour' of Banerjee and demanded that she tender an unqualified apology.

The Left parties joined by Samajwadi Party, Rashtriya Janata Dal and Bahujan Samaj Party in a statement on Thursday said what happened in the Lok Sabha was not only unparliamentary, but an affront to the parliamentary system.
